My invention relates to calendars, being particularly adapted to that type of calendars where a casing is provided which holds a series of plates or discs slideable within the casing. A primary feature of the invention is to provide means for closing one opening of the calendar casing when the other opening is open to expose the date.

My calendar includes a rotatable casing having slideable members within the same upon which the days of the month are designated by numerals or otherwise and wherein the casing is provided on each slide .with openings to disclose the numerals. When the casing is rotated the plates are adapted to slide into position to expose the proper date through the opening in the casing on the front of the same, and I provide means for automatically closing and opening the other side or back of the casing so that when one side of the casing is opened to disclose the date, the other side is closed.

My calendar is automatic and perpetual, being adapted to be readily set for the particular day of the month and to indicate the date when set.

These features, together with other details and objects of the invention will be more fully and clearly set forth hereinafter. In the drawing forming part of the specification:

Figure l isa perspective view of my perpetual calendar as it would appear in use.

Figure 2 is a side View of the same showing therotation of the rotatable member.

Figure 3 is also a side view of the partial rotation of the rotatable member.

Figure 4 is a section longitudinally through the rotatable member.

Figure 5 is a detail of one of the closures for the rotatable member.

Figure 6 is another form of closure for the rotatable member.

My automatic perpetual calendar A is provided with a base B of a suitable nature to support the standards 10 projecting upward from each side of the base B. The standards 10 are adapted,

to pivotally support the rotatable member C by the studs 11 which extend through the side of the casing of the member C.

The rotatable member C is rotatable on the studs 11 as indicated by the arrow in Figure 2. and is formed with comparatively fiat sides 12 and 13. The sides 12 and 13 are formed with display openings 14 and 15 respectively through which the slideable members 16 are adapted to be disclosed to display the particular day of the month such as is illustrated by the member 16 which indicates the numeral 1 indicating the first day of the month.

The rotatable member C, in its operation, rotates to permit the slideable plate members 16 to slide past the division member 17 positioned within the rotatable member C, through the openings 18 on each side of the member 17. The opening 18 is virtually the same width as the thickness of the plate 16 so that only one plate 16 may slide through either of the openings 18 at one time, when the rotative display member 0 is rotated on its axis formed by the studs 12.

The base B may be provided with a rotatable dispay disc E, a portion of which is illustrated through the opening 19 in the front of the base so as to disclose the particular month of the year. In this manner the perpetual calendar may be operated to indicate any particular month in the base and any day, by the rotatable member C. The plates 16 are provided with numerals for each day of the month and thus if the rotatable member C is rotated, the plates 16 slide into position to indicate this numeral for the particular day, and thus can be set so as to provide a perpetual calendar.

In a perpetual calendar of this nature it is de sirable to provide means for closing one of the openings 14 or 15 when it is in operable position to indicate the particular day desired. I have therefore provided in my perpetual calendar suitable automatically operable shutters or closures F, one for each side 12, and 13.

These closures or shutters F are adapted to be pivotally supported by the ears 20 so as to hang freely adjacent the sides 12 and 13 respectively and in the rotation of the member C these shutters are adapted to open and close the openings 14 and 15 in accordance with the position of the same.

It will be noted that the shutters F open automatically in therotation of the member C so that when eitherthe opening 14 or 15 is at the top and front of the calendar A, the shutter F will hang down with the inner surface 21 of the shutter exposed on the lower front portion of the member C. This surface may carry suitable display material such as 22 for advertising purposes or for monograms or any suitable display means. When the shutter F hangs in open position as is illustrated in Figure 1, it discloses one of the plates 16 through the opening 14, the other shutter F on the surface 13 which is at that time considered the back of the rotative member C, closes the opening 15 which is positioned on the opposite side to the axis or center of the rotative member C. Thus the back of the calendar A is closed when the front is open.

This is quite important as it discloses only one display side at one time for the same, and gives a desk utility of a neat and attractive nature.

My calendar A also provides means of automatically opening and closing the different sides of the calendar in the rotation of the same. The shutters operate automatically by gravity to rotate into open and closed position. In operative position the shutters F always hang down toward the base B. This adds a suitable bearing weight to the sides of the rotor C, which has a tendency to hold the rotor C in proper upright position to disclose one of the openings 14 or 15, and to display the particular date which the calendar is set to disclose, while the back is entirely closed, as will be readily apparent.

My calendar provides a utility for advertising purposes or for display or monograms or names, or any other suitable display material on the inside 21 of the shutters F, and when either of the shutters are in position to close the back of the calendar, this display is closed toward the inside of the calendar A.

The shutters F may be formed rectangular from a single piece of material with projecting lugs 24 for pivotally supporting the same in the ears 20 to the rotor C, or these shutters F may be formed in other shapes such as illustrated in Figure 6 so that a very attractive shutter structure may be provided for the sides of the rotor C.

In accordance with the patent statutes, I have described my perpetual automatic calendar, and while I have illustrated the particular formation thereof, I desire to have it understood that this is only suggestive of a means of carrying out the principles of my invention, and that variations may be made within the scope of the following claims without departing from the spirit of my invention.

I claim:

1. A calendar comprising a rotor having slidable display plates therein, openings in each side of said rotor, outside shutters pivotally attached to said rotor for closing and opening said openings in the rotation of said rotor and display surfaces on the inside of each of said shutters.
